Great stuff! The only thing I would suggest is to not jerk so much when doing the move to Crazy Man's Handcuffs. Your motions before that look natural but that one jerk motion would issue that something went on. I feel that the reactions could have been a tiny bit stronger if there were no jerkiness.
Also, don't wear sunglasses when performing for people. Juan Tamariz discusses this in The Five Points in Magic when discussing the Eyes. Your eyes are one of the main keys to misdirection, and the eyes display emotion and what you feel throughout the course of your performance. If you are wearing shades, your audience can't SEE you more clearly as a performer. It seems like you are a strange guy and there is no depth in your magic.
Keep up the performing Alfie, you're doing a great job!
